PROTECTING DEVICE FOR BEDS.

Specification of Letters Patent. Patented N 12, 1918,

Application filed November 22, 1915. Serial No. 62,718.

To aZZ whom it may concern:

Be it known that I, MEYER D. COHEN, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Protective Devices for Beds, of which the following is a specification.

My invention relates to improvements in protectinqdevices for beds.

The object of my invention is -to provide means for protecting bedding from vermin, such as bed bugs, by making it diflicult for the vermin to reach the bedding and also by facilitating their extermination in case the mattress or bed clothing becomes infested with them.

A further object of my invention is to provide means for retaining a mattress in shape and in position upon'a bed spring.

In the drawings- Figure l is a plan view of a bed spring and a portion of a mattress, showing my in vention applied to one end thereof.

Fig. 2 is a perspective view of one end portion of a bed spring and mattress with my invention in position of use.

Fig. 3 is a sectional view, drawn on line o2-ac of Fig. 1.

Like parts are identified by the same reference characters throughout the several views.

A is a bed spring, A the spring supporting frame bars, and B a mattress supported by the spring in the ordinary manner, except that at the ends a metallic shield is employed which covers the ends of the sprlng and mattress and also a portion of the sides thereof adjacent to the ends, said shield being further provided with a member adapted to be interposed between the spring and the mattress at each end.

The shield illustrated in the drawings is formed in sections and comprises a back wall composed of the wall sections 0, C with end walls I), D, and inwardly projecting medial flanges E, E, respectively. The back wall members C, C, lap upon each other, as best shown in Fig. 4, the flange E being slotted at e to receive the wall C. A sliding plate F is mounted upon the flange E adapted to cover the open portion of the slot 0. This sliding plate F may be secured a slot f in the flange E, whereby the plate may be moved longitudinally and adjusted to cover the slot 0 in any desired position of extension of the back wall member C. By thus making the shield in sections, it is possible to adjust the shield to mattresses which difier in width.

The shield is preferably formed of metal or other suitable material having a hard smooth surface to which the bed bugs cannot cling. I have found that bed bugs almost invariably enter a bed from the corners and that they will not or cannot climb vertically over a smooth hard surface. With my improved shield the bugs attempting to enter the bed from the bed frame or corner post, are obliged to climb around the shield in order to reach the mattress, and if the bed clothing is properly disposed by tucking it around the mattress within the shield, it will be impossible for the bugs to reach the bedding. I have also found that where the bedding is already infested with bugs, the destruction of the bugs is greatly facilitated by' applying my shield to the spring and mattress, as illustrated in the drawings preparatory to the use of an insecticide. Upon being affected by an insecticide, the bugs immediately travel to the corners of the mattress. By placing quantities of the insecticide in the corners and angles of my im'- proved shield, the bugs collecting in such corners and angles are readily destroyed, instead of being permitted to escape.

My shield is also useful in retaining the mattress upon a bed spring and preventing it from spreading or getting out of shape.

It will be observed that the back and end walls C, C and D, D, extend downwardly below the horizontal flanges E, E, so as to.

cover the ends of the spring frame. This is preferred, for the reason that bugs which have reached the spring frame will invariably crawl toward the corners of said frame in attempting to pass to the mattress and at these corners they will find access to the mattress barred not only by the horizontal flanges, but by the downwardly extending portions of the back and end walls, so that it would be necessary for them to climb downwardly along these smooth surfaces and around the lower edges of the shield and then upwardly in order to reach the mat and end Walls extended downwardly below tress. This the bugs cannot or will not do. said flange to cover theyends of the spring I claimframe, substantially as specified.
